To investigate the clinical efficacy of laparoscopic totally extra-peritoneal hernia repair (TEP) for incisional hernia of the abdominal wall.

A total of 138 patients with incisional hernia of the abdominal wall were selected from April 2022 to April 2023 in Beijing Tongren Hospital, Capital Medical University. According to different surgical methods, 54 patients who underwent TEP were divided into the laparoscopic group and 84 patients who underwent open mesh repair were divided into the control group. The differences between the two groups were compared in terms of perioperative condition and recurrence rate one week after operation.

The patients in the laparoscopic group had lower incidence of complications (poor incisional healing, incisional infection, scrotal edema, scrotal hematoma, urinary retention and foreign body sensation hardening) than the control group, and the difference was statistically significant (P<0.05). The operative time, hospital stay, intraoperative bleeding, and recurrence rate were lower in the laparoscopic group than those in the control group, with statistically significant differences (P<0.05). The visual analogue scale (VAS) scores were lower in the laparoscopic group than that in the control group at 24 h postoperatively, with statistically significant differences (P<0.05). There was no significant difference in VAS score between the two groups at 48 hours after operation.

Laparoscopic TEP hernia repair was safe and reliable, with the advantages of short operation time, less trauma, rapid postoperative recovery, and few complications.
